If `curl -i` does not give you any [headers as sent by the server](https://www.thethingsnetwork.org/forum/t/having-trouble-sending-downlink-with-http-integration/38217/2), then this is some weird problem (with a weird message) from your local system, not from TTN’s server. Maybe some hidden newline in the command line?

Note that only the key is secret; redacting the other parts of the actual command you’re using is just adding confusion.
